This isn't so much of an update as a few small tweaks. I've just fixed any bugs that I've found, mainly in the drawing your own seabed geometry section, and added in a control for density which just effects how the different size Plankton elements behave in the currents. By adding this I could also add gravity so that Plankton can sink...

This really is the final release of Plankton, v1.3. I've expanded some features such as allowing users to specify custom specific brushes for the plankton, background and sea bed. This includes support for ImageBrush with added UI options so that image scan be used for these elements. I've also added a texture generator for the sea bed...

So, you know when you get bored at work and one thing leads to another... you start coding something fun, add a few options, revise it a bit and before you know it you've wasted a few hours, well Plankton was one of those moments. It's a small little program, not really a game, certainly not a simulator, just a... programming moment.
